Question

example for valency​

Answer 1

Explanation:

For example, oxygen has six valence electrons, but its valency is 2. Some elements may have more than one combining power (or valency), while others have just one. For example, H →1; Mg→2; Al→3; C→4; N→3, and 5; P→3 and 5; O→2; S→ 2, 4 and 6; Cl→ 1; and Ne→0.
